Each of a plurality of pixels is composed of a first sub-pixel for a first color, a second sub-pixel for a second color, and a third sub-pixel for a third color. The longitudinal direction of the first sub-pixel is the extending direction of video lines, and the longitudinal direction of each of the second sub-pixel and the third sub-pixel is the extending direction of scanning lines. The second sub-pixel and the third sub-pixel are arranged adjacent to each other on one side of the first sub-pixel. The first sub-pixels are continuously formed in two adjacent pixels in the extending direction of the video lines. When three adjacent pixels in the extending direction of the video lines are defined as first to third pixels, the second sub-pixels are continuously formed in the first pixel and the second pixel, and the third sub-pixels are continuously formed in the second pixel and the third pixel.
